Icelake with integrated TB3 controllers completely crushes non-Icelake CPU's with external controllers in performance (up to 40% gains...)

I was alerted to Jarod Tech's findings on NotebookCheck and immediately jumped here for the discussion. I'm very keen to setup a solid ultrabook eGPU setup for when I'm working on-site with an RV. This is encouraging!

I'm also very curious how Thunderbolt 4 will play out. Looking forward to seeing those benchmarks.

I got an HP Spectre X360 [15-eb1043dx] yesterday with the i7-1165G7 processor. Thanks to the 15-in footprint and no dGPU, the cooling system is working surprisingly well. The CPU is set at 28W and can run consistently at 3.3GHz and temps hovering around low 70s Celsius. I let AIDA64 System Stability test run for over an hour and the laptop was not even warm to the touch. As seen in the photo below, the warmest spot in the middle top half of the keyboard was mid 30s Celsius. Noise was not bad either at low 50s dB.

Thunderbolt 4 is not necessarily faster than Thunderbolt 3. As with most things we've learned about this technology, every component of an eGPU setup can make a difference. You'd want the best host laptop possible in order to extract the most performance out of the external graphics card. The go-to configuration is direct Thunderbolt connection to the CPU. Ice Lake and now Tiger Lake provide that ideal connection. With the exception of Alienware and Apple 15-in/16-in MacBook Pro, most H-CPU laptops route their Thunderbolt connection through the PCH and the manufacturers don't care how it performs in eGPU mode.

Next is the CPU TDP and its cooling system. I'm a firm believer in iGPU-only ultrabook. There's only one main component to cool and it keeps things simple regarding graphics switching. This HP Spectre X360 15 is a very good example of what a perfect eGPU host in late 2020 should be. I will post a build guide soon with benchmark numbers.

Jarrod did a comparison a few months back of Ice Lake 10th Gen i7-1065G7 vs "Comet Lake" i7-10750H using a 3090 eGPU.

I was expecting the 6c/12t higher TDP part to run away with it or at least be more competitive but I suppose the on-die TB controller makes THAT much of a difference. Making me rethink considering an 11th Gen Tiger Lake laptop as my next. There's quite a few decent ones out there like the MSI Prestige 15 (can just disable the dGPU). It's too bad LG didn't use some of that extra room in their new 11th Gen Gram to bump it up to 28W. It also looks like the 35W i7-11375H has an embedded TB4 controller, so perhaps when we see some units sporting that it'll be the best platform.

Sorry if it's old news, I was just a little surprised how much the gap is between the two given how much more powerful the 6c CPU is. 

EDIT: Sorry guys I searched for a thread like this and didn't see one. Thanks mods for closing that thread and moving the post here. Smile

This RedmiBook Pro 15 with the i7-11370H sounds exactly like what all of us may need.

Any rumors of upcoming Alder Lake higher core count CPUs having embedded TB4 controllers?

I had the HP envy 14 with the 1135g7 and there is still thunderbolt issues with warzone. Which makes me believe they fixed the latency issues (high fps) but not the small block performance. (low fps in downtown with low bandwidth usage)

 

I have a Razer Stealth 11th gen on order to see if that machine fairs any better with my 2070 eGPU.

@odin, If the RedmiBook Pro 15 has a good cooling system, its eGPU performance will be excellent like the ASUS TUF Dash F15 [build link].

It'll just be a risk for anyone that's in the US to buy one, they don't typically sell in US markets I don't think so warranty will be difficult to use if there's an issue with it. It would be nice to see that change, but I don't have high hopes.

@odin, I have been keeping an eye on the newest LG Gram lineup. The 16-in model looks very nice. My current LG Gram is still very good for everything except 15W TDP limit in eGPU use. It never gets old picking this laptop up with no effort. LG did an amazing job on weight distribution.

Yeah, I still really like it, I just wish they would use that extra room in the Gram 17 to get better CPU performance. I know it's not really a goal of the product to add any weight for cooling, higher CPU power limit would probably cut into their already fantasized 19hr battery claims and they are saving in manufacturing cost by using identical components up and down the line. It's still a great machine and I don't think I'd sell it, I just want something with some more speed for gaming. With the new H35 and upcoming H45 line having embedded TB4 we don't have to settle for low power anymore. Just remains to be seen what units will exist, it's probably going to be hard to find H45 without a dGPU coming along with it.

To All,

Looking for advice from members with hands on usage.

I am in a position to upgrade but looks like I cannot hold off until the new 11th Gen H processors release. So what would be the best option between the i7-10850h vs i7-1185g7

10th Gen has a higher core count 6c/6t and TDP rating. Yet 11th Gen has 4c/4t and also boasts higher singel core thread performance and Thunderbolt 4 connectivity.

Any advice would be welcome.

 

 

Setup: Dell Latitude 7300 | i7-8665U | 32GB DDR4 | M2.sata 512GB |
iGPU: UHD 620 | eGPU: Nvidia RTX 3070 FE | Asus XG Station Pro | Thunderbolt 3 (15D9) : NVM 44.00
